What is and how to activate the SPF Register

To improve the reputation of emails and allow receiving providers to verify that they are legitimate emails, you can enable an SPF record.

 

The SPF record determines which mail servers and domains are allowed to send email on behalf of your domain. It also tells the servers receiving your email what to do with messages once they have been checked.

 

Those servers check your SPF record to confirm that messages appearing to come from your organization were sent from authorized servers. Domains can only have one SPF record. However, a domain's SPF record can specify multiple servers and third parties that are allowed to send email on behalf of the domain.

 

 

To enable the SPF record, you must follow these steps:

 

1.- Hosting email management

 

Access the hosting management from the "Basic service list" by clicking on the hosting option as shown in the following image.

 

 

On the "Manage hosting" screen, you must go to the email management section and access “Email authentication”: 

When accessing this section, first of all, you will be able to see the DNS status of the domain you are configuring. Our control panel will detect whether you have the DNS servers with us or with another provider. The only implication is that you must configure the records shown later in the corresponding DNS panel. For more information, you can check our tutorial about

how to configure email authentication from the control panel.

 

SPF activation is based on a TXT/SPF type record in the domain DNS section. This usually blocks much of the spam we receive, since the vast majority of it is sent from spoofed addresses to maximize effectiveness, so it is recommended to keep it enabled. The record that is automatically created (Recommended value) only contains the cdmon servers, therefore only emails sent from them are validated. If another server is used to send emails, you can modify the record and include the necessary servers. 

 

In the guide How to configure the SPF record for email in static DNS you will find more information about how to create it manually or modify the SPF record. 

 

Note: Keep in mind that if someone tries to send us emails with a spoofed address or with an incorrectly configured outgoing SPF, our incoming SPF would block the reception of that message.
